💡 Pro Tip: The RectorSeal 83017 sleeve is about 1/2" narrower than the standard 3.5" sleeve used on MRCOOL DIY Series systems. This is because MRCOOL’s Quick Connect line sets have a larger diameter than traditional flare-style lines. You can still use this sleeve with pre-charged line sets — simply separate the individual lines slightly before feeding them through, and finesse the insulation to avoid tearing the inner lining. With a bit of care, it provides a snug, professional-looking fit for DIY installations.
